needing bristlenose info please :)

fryup

well i would like to know everything you can posably tell me about bristlenose plecs....i know the basics like water parments and feeding.....but i would like to know about possably breeding and sexing .....i have 2 plecs ther both still you altho 1 has almost doubled in size and my other is growing more slowly

any help would be apriciated, thanks :)

kitten_penang

i think they have info in the fish directory =)

fryup

i was hoping ppl no info like temp to get them to breed, and the size of the adults when they will breed because my "male" in about 2.5-3 inch and the new small one is around 1-2 inch :):):)

fryup

thanks :):):):)

Breeding takes place in hollows, caves and mud holes in banks. Males may clean the inside of the cavity with their suckermouth before allowing the female to approach and inspect the nest. Courtship includes expanding the dorsal and caudal fins and attempts by the male to escort the female to the nest. While the female inspects the nest, the male keeps close contact.[3] The female may lay 20-200 adhesive eggs, usually to the ceiling of the cavity.[3]
The female plays no role in parental care; the male takes care of its young. Males will clean the eggs and the cavity with its fins and mouth. Males inspect eggs to remove diseased or infertile eggs, and aerates the clutch by fanning them with its pectoral and pelvic fins.[3] During this time, a male usually will not leave the cavity to feed, or will leave only occasionally and quickly return.[3] The eggs hatch in 4–10 days over a period of 2–6 hours; the male guards the eggs for 7–10 days after hatching.[3] The fry remain in the cave, attaching to the walls and ceiling with their mouths, absorbing their yolk sac in 2–4 days and becoming free swimming.[3]
Males of these species are competitive and territorial. Males display to each other by positioning themselves parallel to each other, head to tail, with dorsal and caudal fins erect and cheek odontode spines everted. If this escalates to combat, the males will circle each other and direct attacks at the head.[3] If an intruding male manages to evict another male from the nest, it may cannibalize the other male's young.[3]
A male bristlenose may guard several clutches of eggs simultaneously. Females prefer males that are already protecting eggs and may prefer males that are protecting larvae; it has been suggested that the tentacles may act as a fry mimic to attract females, which would allow males without eggs in their nest to compete with males guarding eggs.[3] Several clutches in various states of development from eggs to free-swimming larvae can be found in one nest.[2]

These fish are often kept by aquarists as they are dutiful algae-eaters and smaller in adult size than the common plecos usually seen in petshops. Size is up to 15 cm (male), 12 cm (female), recommended temperature 23-27 degrees Celsius, lifespan up to 12 years. They are hardy animals, tolerant to a wide range of water conditions, breeding easily in captivity, compatible with most other freshwater fish, though typically mottled brown in colour, other species are more exotic - spots of bright yellow on a dark background being a common patternation, albino variants are also common. It is thought that the eggs of the bristle-nosed pleco are light sensitive, albino fish may be the result of exposure to excesive light.
Historically commonly available species of Ancistrus were Ancistrus dolichopterus and Ancistrus temminckii, other species are now available though exact identification is difficult.
Feeding is easy, bristlenoses will graze on algae and other surface growing organisms as well as eating algae wafers or tablets, flake food, squash, spinach, cucumber, zucchini, green beans and peas however they have been known to accept frozen bloodworms as part of their diet. Aquarium specimens may starve for lack of algae or other plant matter; algae wafers or other low-protein foods are recommended. Keepers should watch for the abdomen to take on a sunken appearance, indicating insufficient nutrition.
Like other plecs benefit from the addition of bogwood, which they will rasp at and use as a hiding place - in the absence of other plant matter (sources of fibre) wood may be essential to the survival of these fish in the aquarium as it helps digestion of typically high protein fish food.[6]
Sexing is very easy as the female will occasionally have bristles around the edge of the chin and the male will have them up the center of the head
Breeding is also possible: Males attract females to small cave or hollow, then guard eggs after fertilization through hatching (4-8 days) until fry are free swimming (4-6 days after hatching); the aquarist need only supply a suitable cave, food, and one of each sex.
Caution should be taken with the spines (odontodes) - although the risk of personal injury is small with this genus the hooked nature of the odontodes means that a bristlenose may become trapped in non-natural material such as sponge filters and netting.

wow thanks thats really helpful i will remember this :) .....1 other question i have a lot of snails in my tank (i dont mind them beeing there) will the eggs be ok or will the snails eat them ??? :):):)

kitten_penang

umm.. i never had snails before but i think certain types will eat the eggs as it's a good source of protein. better get rid of them first or let the pleco parent deal with them but i don't think plecos eat snails =S

fryup

well i dnt really wana get rid of them but i would like my plecs to breed :S....hmmm! wot to do now?...well i know my plecs dont eat the snails eggs and the snails dnt eat snail eggs so do you think they will eat plec eggs???

:):):)
